29. 5/2× 2/5×=5/2×7 multiply the equation by the reciprocal of the coefficient
x= 5/2×7/1 <span> reduce the numbers with 5,2. convert the expression into a fraction
</span><span>
x= 5</span>×7/2×1
<span>
x= 35/2
32. a= 19/6
2 3/4a = 19 1/4 divide both sides of the equation by 1/4
2</span>×3a=19 calculate the product <span>
</span>
6a=19 divide both sides by 6
a=19/6
